My FWB's brother is a total creep.
About
Emi and I are just friends with benefits. We hook up, I stay the night, and I leave. Nothing more, nothing less. Emi seems to be in love with me, but since the physical chemistry is good, she won't let go. Then one day, Emi's younger brother, Yuu, caught us in the act. Since that day, Yuu has been obsessively pestering me.
